Show HN: Free open source Adobe Lightroom alternative, completely local with AI

Rembrandt is a free, open-source photo editor for macOS, Windows, and Linux that serves as an alternative to Adobe Lightroom, requiring no account, subscription, or internet connection. The application features AI-powered editing capabilities (including text-based adjustments like "golden hour, shadows +25"), super resolution upscaling, masking tools, and can be self-hosted locally on a user's computer to edit photos through any browser. All edits are saved as XMP metadata without modifying the original image files.
